Antagonistic fungi such as Trichodermaharzianum (T1, from bean field in Ahvaz,Tz, from chickpea field in Karaj), T.vride (T3, from bean field in shahriar, T4, from collection of plant pest & Diseases Institute, Tehran), T.koningii(T5, from Science & Technology Research organization), Gliocladium virens (Gi & G2, from chickpea field in Karaj ) were used to control chickpea root rot incited by Fusarium solani and their effect on weight of chickpea plants. The experiment was carried out in a completely randomized design in pot under greenhouse conditions . The results showed that the antagonistic fungi decreased root rot 40,56,69,44,64,36 and 32% respectively in respect to inoculated control . The antagonists in order of efficacy were T3>T5>T2>T4>T1>G1>G2. Effect of the antagonists on the weight of chickpea plant were T5 >T2>T3 >T1 >T4> G1 > G2 respectively .The use of the antagonists in the non-inoculated soil with the pathogen had no any effect on the weight of chickpea plants.
